Title: Processing device for end face of plastic optical fiber
Inventor: TANEICHI SEISHIRO
IPC: G02B6/00
Filed: 1988-02-29
Abstract: PURPOSE:To eliminate the necessary of lowering the temperature of an end face forming plate so as to reduce the processing time of end face formation of a plastic optical fiber by adopting radiation heating using far infrared rays so that only the optical fiber can be heated. CONSTITUTION:A heating body 1 of a far infrared ray radiating body and an end face forming plate 3 made of a substance having a good far infrared ray transmittance are provided. Since the far infrared rays radiated from the heating body 1 are mainly absorbed by a plastic optical fiber 5, the end face of the optical fiber 5 is directly heated and deformed. On the other hand, the plate 3 is not heated so much because of its good far infrared ray transmittance and its temperature rise is suppressed to lower than the thermo-deforming temperature of the optical fiber 5. Since the end face of the optical fiber 5 deforms while the fiber 5 is pressed against the plate 3, whose temperature is lower than that of the end face, the optical fiber 5 can be brought to the next process without lowering the temperature of the plate 3 after processing. Thus the processing time can be made shorter.

Title: Position register system of pocket bell
Inventor: ISHIKAWA HIROSHI
IPC: H04W4/00
Filed: 1983-03-23
Abstract: PURPOSE:To increase a service area by registering the position of a pocket bell in response to a new calling area when the terminal of the pocket bell is shifted to another calling area. CONSTITUTION:A pocket bell terminal 4 belonging to a home exchange station 11 moves to a calling area 2, and the identification number of the area 2 is displayed at a display part 45 of the terminal 4. Then the identification number is informed to an attached home exchange station 21. The station 21 registers the number of the area 2 where the terminal 4 exists in accordance with said identification number and at the same time calls out the terminal 4 by the identification number which is newly registered. Then the station 21 erases the display of the part 45 and confirms the registration. In such a way, the position of a pocket bell is registered in response to a new calling area. Thus the service area of the pocket bell can be optionally increased.

Abstract: PROBLEM TO BE SOLVED: To improve the cold workability of an alloy by cooling a double phase Al alloy material contg. ductile Al base phases and secondary phases hard to deform to a very low temp. of the liq. N temp. or below, introduce microcracks into the secondary phases by multipass cold working and parting and crushing these microcracks. SOLUTION: This double phase Al alloy contains Si, Fe, Cu, Mn, Mg, Li, Zn or the like in addition to Al as the main component. As for the cooling of this alloy material, the execution at a low temp. as possible is advantageous, and, in consideration of the actual working, it can be made to the range to the liq. He temp. More practically, the cooling temp. or below with liq. nitrogen as a cooling medium is preferable. As the multipass cold working, swaging, groove rolling, flat rolling or the like at a relatively light draft can be executed. Moreover, by repeatedly combining recovery heat treatment and low temp. cold working, cracks generated in the cold working at a low temp. are eliminated, and by the second cold working at a low temp., only the secondary phases are crushed and parted.

Abstract: PURPOSE:To reduce series resistance, and to improve the performance of an FET by combining a method by ion implantation and a method by impurity diffusion from the surface for forming source-drain regions and increasing carrier concentration on the surface side. CONSTITUTION:Be ions are implanted to a semi-insulating GaAs substrate 21 by using a mask 22, and an ion implantation layer is activated through heat treatment. WN24 is deposited on the whole surface of a wafer as a gate metal, and a gate pattern 25 is formed by a photo-resist. WN24 as the gate metal is processed, using the photo- resist as a mask. An SiO2 film is deposited on the whole surface of the wafer, and a side wall 26 is shaped on the side surface of the gate electrode 24 through etching. Mg ions are implanted to sections as a source region 27 and a drain region 28 through self-alignment to the gate electrode, and SiO229 containing Zn is shaped through a spin coating method. SiO229 containing Zn is etched by using a mask 30. Zn is diffused from the SiO2 film 29 through heat treatment in the atmosphere of AsH3+Ar to form the source region 27 and the drain region 28.

Abstract: PURPOSE:To execute a uniform development processing extending over the whole of a body to be developed by observing an advance state of a development processing in different positions of the body to be developed, respectively and performing the development processing in accordance with an advance state of an observation spot. CONSTITUTION:A master disk 101 to which an exposure processing has been performed is placed on a turntable 25, and thereafter, it is driven to rotate at a constant speed. After a pre-rinse has been ended, a developer D is discharged or ejected like a spray from developer nozzles 21a-21c, by which a photoresist of a latent image part which has been formed by the exposure is eliminated. An advance state of this development processing is monitored by monitoring the intensity of each diffracted light by laser beams 33a-33c which have been radiated to the master disk 101. For instance, the discharge quantity of the developer D discharged from the nozzle 21a is controlled in accordance with the advance state of the development processing which is monitored by a detector 7a provided on a position corresponding to the nozzle 21a.

Title: El emitter
Inventor: ITO HIROTAKA
IPC: H05B33/10
Filed: 1989-02-28
Abstract: PURPOSE:To prevent an activity drop of a light emitting layer caused by moisture by using a fluorocarbon polymer for a resin binder at a transparent electrode layer and a light emitting layer. CONSTITUTION:A fluorocarbon polymer is used for a resin binder at a transparent electrode layer 4 and a light emitting layer 5. Thus, the fluorocarbon polymer is used for a resin binder in case of a transparent conductive paint where a transparent conductive imparting agent is contained/dispersed and a resin liquid where a phosphor is contained dispersed so that a transparent electrode layer 4 and a light emitting layer 5 are formed as coating layers of those paint and resin liquid. Thereby, a decrease in luminance caused by getting away from a reed electrode can be remedied; and the light emitting layer 5 can be prevented from a drop of activity due to moisture because the fluorocarbon polymer is low hygroscopic.

Abstract: PURPOSE:To enhance inspection accuracy and inspection efficiency, by making it possible to automatically and accurately set timing from the point of time when a position signal is stored to the point of time when the reading thereof is started by providing a center position detecting circuit and a timing means. CONSTITUTION:The binarizing signals from CCDs 9, 10 are changed over from a judge circuit 14 to a delay time setting circuit 17 by changing over switches 18, 19 by a control circuit 22 and, when a through-hole 3 arrives above a lens 7 and the CCD 9, the image signal of the hole 3 is read by the CCD 9 to be successively sent to a two-dimensional shift register 21. A radial sensor 21-1 is incorporated in the register 21 and the signal from the sensor 21-1 is sent to a center position detecting circuit 23. When the image signal of the hole 3 is taken in the register 21 and the sensor 21-1 detects that the center of the image of the hole 3 passes, a signal (a) is sent from the circuit 23 and a counter 24 starts the counting of a clock CLK. By this method, a delay time is automatically set by a delay time setting circuit 12.
